no tes:
R in cer tain driving and driving saf ety sy stems,
th e sensors adjust automatically while a cer‐
ta in dis tance is being driven af terth eve hicle
has been delivered or af terre pairs. Full sys‐
te m ef fectiveness is not reached until the
end of this teach-in process.
R brakepads, brake discs and tyres that are
either new or ha vebeen replaced only ach‐
ie ve optimum braking ef fect and grip af ter
se veral hundred kilom etre s of driving. Com‐
pensate forth ere duced braking ef fect by
applying greater forc eto the brake pedal. Note
s on optimised acceleration If all necessary
requirements and activation con‐
ditions are fulfilled, the best possible accelera‐
tion can be achie ved from a standstill.
Do not use the optimised acceleration on public
ro ads. Individual wheels could spin and youcould lose control of
theve hicle. There is an
increased risk of skidding and/or accident.
Be sure toobser vethe saf ety no tes and informa‐
tion on ESP ®

WARNING Risk of skidding and having
an accident from wheels spinning
When you use optimised acceleration, indi‐
vidual wheels could spin and you could lose
cont rol of theve hicle.
If ESP ®
is deactivated, there is a risk of skid‐
ding and accident! #
Make sure that no persons or obstacles
are in the close vicinity of your vehicle. Re
quirements:
R theve hicle is run in (/ page 155).
R theve hicle and tyres are in good condition.
R you are on a high-g rip ro adw ay.
R the engine and transmission are at normal
operating temp erature. *

TEIncreased wear due tooptimised
acceleration When pulling
away with optimised accelera‐
tion, all components of the driv etra in are
subjected toave ry high load.
This can lead toinc reased component wear. #
Do not alw ays pull away with optimised
acceleration. #

a qu alified specialist workshop. *
NO
TEReduced battery life due tofre‐
qu ent short-dis tance trips The
12V battery may not be suf ficiently
ch arge d when theve hicle is used only for
short-dis tance trips. This reduces the life of
th e batter y. #
Drive longer di stances regular lyto
ch arge the batter y. Note
s on driving with a roof load, trailer or
fully laden vehicle
When driving with a loaded roof luggage rack or
trailer as well as with a fully laden or fully occu‐
pied vehicle, theve hicle's driving and steering
ch aracteristics change. Yo
u should bear thefo llowing in mind:
R Do not exceed the permissible roof load and
to wing capacity. Also obser vethete ch nical
da ta inthe printed Owner's Manual.
R Evenly distribute thero of load, and place
heavy objects at the bottom. Also comply
with the no tes on loading theve hicle
(/ page 108).
R Drive attentivel y,and avoid sudden lypulling
aw ay, braking and steering as well as rapid
cornering.
Note s on driving on salt-treated roads
The braking ef fect is limited on salt-trea ted
ro ads.
Therefore, obse rveth efo llowing no tes:
R due tosalt build-up on the brake disks and
brakepads, the braking dis tance can increase
conside rably or result in braking only on one
side
R maintain a much greater safe dis tance tothe
ve hicle in front To
remo vesalt build-up:
R brake occasionally while paying attention to
th e tra ffic conditions
R carefully depress the brake pedal at the end
of the journey and when starting the next
journey
Note s on aquaplaning
Aq uaplaning can take place once a cer tain
amount of water has accumulated on thero ad
sur face.
Obser vethefo llowing no tes during heavy precip‐
itation or in conditions in which aquaplaning may
occur:
R reduce speed
R avoid tyre ruts
R avoid sudden steering mo vements
R brake carefully
